The Alti Double Hung composite window is unique in the New Zealand market.
Our special patented system means that no aluminium colour is visible from the inside of your home.
The Double Hung is a wonderful complement to traditional homes - especially in combination with classic colonial glazing - and can also add style and
function to modern homes.
The profile has a smooth classic timber appearance and an easy clean powder-coated aluminium sill.
Quality balance systems ensure that these windows open and shut with ease, and can accommodate over height double glazed units.
Double Hung windows can be banked to create a special ventilated bay area. And for those looking for additional ventilation, overlights can be easily
fitted on top of your Double Hung windows.
